Abstract

An electrical transmission cable incorporating coaxial cables, power supply cables, data conductors and telephone conductors suitable for use in residential wiring is disclosed. Cable comprises a bundle configuration in which coaxial conductors are disposed in a center of a round bundle between data and telephone conductors to reduce the continuation of signals in the data and telephone conductors.

Claims

1. A distribution cable for transmitting electrical signals without excessive crosstalk, comprising

at least one coaxial signal conductor having a braid surrounding a center conductor;

at least one first unshielded signal conductor;

at least one second unshielded signal conductor, each at least one said first and second unshielded signal conductor extending parallel to the at least one coaxial conductor, where said at least one first unshielded signal conductor is disposed on the opposite side of the at least one coaxial conductor from the at least one second unshielded signal conductor, and said at least one first unshielded signal conductor and the at least one second unshielded signal conductor are disposed in a common insulative web, the insulative web being wrapped at least partially around the at least one coaxial conductor; and

an insulative sheath surrounding said insulative web to retain the at least one first unshielded and at least one second unshielded signal conductor on opposite sides of the at least one coaxial conductor, so that crosstalk between the at least one first unshielded signal conductor and the at least one second unshielded signal conductor is reduced by the braid of the at least one coaxial conductor.

2. The distribution cable of claim 1 further comprising a plurality of power conductors disposed at least partially between the at least one first and second signal conductors, the power conductors being disposed in the common insulative web.

3. The distribution cable of claim 2 including two coaxial conductors wherein a portion of the insulative web between two of the power conductors extends between the two coaxial conductors.

4. The distribution cable of claim 1 wherein the at least one first unshielded signal conductor comprises a plurality of conductors of the type suitable for the transmission of digital signals.

5. The distribution cable of claim 4 wherein the at least one second unshielded signal conductor comprises a plurality of conductors of the type suitable for the transmission of analog signals.

6. The distribution cable of claim 5 wherein the second unshielded conductors comprise conductors for the transmission of telephone signals.

7. The distribution cable of claim 6 further comprising a plurality of first power conductors and a plurality of second power conductors.

8. The distribution cable of claim 7 wherein the power and unshielded signal conductors are disposed within common insulative web, the first power conductors being disposed adjacent one end of the common insulative web, the second power conductors being disposed between the first unshielded signal conductors and the second unshielded signal conductors.

9. An electric cable comprising a plurality of unshielded conductors for transmitting a plurality of signals at frequencies sufficient to induce crosstalk between unshielded conductors, the cable comprising an initially planar insulative web containing the unshielded conductors in side by side relationship, the insulative web being wrapped around at least one coaxial signal conductor having a braid surrounding a center conductor, so that unshielded conductors on one side of the at least one coaxial conductor are shielded from unshielded conductors on the other side of the at least one coaxial conductor by the braid of the at least one coaxial conductor to reduce crosstalk therebetween.
